And now, after fiddling around with random settings, then going through the same HDMI connection test, the Roku now says “This HDMI connection can play video at resolutions up to 4K/Dolby Vision.” I don’t know what’s going on. Is this some sort of bug in this Roku device?
I went into the Roku’s settings and tested the HDMI connection. The Roku device returned a message that states “This HDMI connection can only play video at resolutions up to 1080p because HDCP 2.2 is not supported...”
Meanwhile, I’m looking at the specs for my TV and it clearly lists that it...
Everything is already connected via the receiver.
For the Roku, I have a wired internet connection. My internet speed is 408.11 Mbps for download and 22.31 Mbps for upload, according to Speedtest.
Just in time for the New Year, I finally upgraded my media room to 4K, installing these devices...
